I wouldn't do too much straight after the birth just because it can be a bit uncomfortable to walk for the 1st few days to a week (it was for me anyway). I also had low milk supply with both my kids to start so I wouldn't do to much until my milk supply was established....this could be totally different for you.

Other than that I can't see why you can't go out for a walk and do a workout at home. I have had 2 very easy babies who have worked in with what I want to do, both mine were dragged around shopping from 4 days old and my DS was out shopping with me almost every day. Its a little harder with 2 but I still manage to get out at least 4 or 5 times a week.

I was told before my 1st baby that I wouldn't have time to sit and have a coffee at a coffee shop....I have definitely prooved that person wrong and I am now doing that with 2 kids.

I don't do much exercise but I do get on my exercise bike and ride approx 6kms a day....not today though I am too tired LOL
